hello, can someone help me with some advice please?
I have a mercedes b180 cdi from 2007, I close the doors with the key but after 3 minutes I can't open the doors at all with the key.
the rear doors have both had that bouncing actuators for some time... is there any connection? I also have an alarm system error on board

You need to scan it. All doors will have modules that may reveal a code. Any water leakes at all? Look for the SAM posts. I'm not sure exactly what it controls in the B180 but for most MBs it controls just about everything internally, door locks, windows, elec seats etc. Buy yourself a decent scan tool like an Autel or icarsoft V3. If you have fault codes theyll show up there and point you in the right direction.
I think the SAM is behind the glove compartment under the front dash.
